Android Material ToolBar SearchBar/SearchView Example – How to filter
search a simple ListView and handle onclicks.

So let’s see how to filter/search a simple ListView from the toolbar using a material design searchbar. We’ll place our searchbar/searchview in the appbar and filter our listview in realtime as the user types data in the searchbar.

We use ArrayAdapter to populate our ListView from a simple arraylist. This then helps us in filtering as the arrayadpter instance gives us a Filter object that helps us easily implement a basic filter.

Common Questions this example explores

• Android Material ToolBar SearchBar ListView example.
• Android Filter or Search a ListView.
• Realtime search listview using searchview.

Tools Used

This example was written with the following tools:

• Windows 8
• AndroidStudio IDE
• Genymotion Emulator
• Language : Java
• Topic : Material SearchBar, ToolBar SearchBar, ListView Search Filter

Libaries Used

• We use Material SearchBar library https://github.com/mancj/MaterialSearchBar by Mansur.

Source Code

Lets jump directly to the source code. [su_tabs] [su_tab title=”Build.Gradle Project Level”]

• Our project level build.gradle.
• We add repositories for fetching our dependencies here.
• The dafult,jccenter() is already specified.
• However, we add the maven and specify the url we’ll use to fetch our Material SearchBar here.

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Build.Gradle App Level

• Our app level build.gradle file.
• We specify compilesdk,minimum sdk,target sdk and dependencies.
• Note that the minimum sdk must be API level 16 Jelly bean for us to use the Material Searchbar library that we use here.
• We also add dependencies using ‘compile’ statement.
• Our activity shall derive from the appCompatActivity to make it target earlier android versions.
• We also specify design support library.
• Finally we add the com.github.mancj:MaterialSearchBar which is a third party library we’ll use to display Material Searchbar.
• You then sync the project.

MainActivity.java

• Our MainActivity class.
• Derives from AppCompatActivity which is a Base class for activities that use the support library action bar features.
• Methods: onCreate().
• Inflated From activity_main.xml using the setContentView() method.
• This method is responsible for filtering/searching a gridview via a material serahcbar displayed inside a toolbar.
• The views we use are Material Searchbar for searching and GridView to be searched.
• Reference MaterialSearchBar and GridView from our layout specification using findViewById().
• Instantiate adapter and set it to GridView.
• Add TextChangeListener to MaterialSearchBar and use arrayadapter instance to filter data.

ActivityMain.xml

• ActivityMain.xml.
• This is a template layout for our MainActivity.
• Root layout tag is CoordinatorLayout from design support library.
• CordinatorLayout is viewgroup that is a superpowered on framelayout.
• CoordinatorLayout is intended for two primary use cases: As a top-level application decor or chrome layout As a container for a specific interaction with one or more child views
• Inside our CordinatorLayout we add : AppBarLayout,FloatingActionButton and include content_main.xml.
• AppBarLayout is vertical LinearLayout that implements scrolling features of material design concept.
• It should be a direct child of CordinatorLayout, otherwise alot of features won’t work.
• Inside the AppBarLayout we add our toolbar,which we give a blue color.
• Next we add our Material SearchBar which will give us the searchbar.
• We can specify attributes like style and hint.
• We will add our widgets in our content_main.xml, not here as this is a template layout.
• Finally we have a FloatingActionButton, a class that derives from android.support.design.widget.VisibilityAwareImageButton. Its the round button you see in our user interface.

<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.CoordinatorLayout 
    
    
    android_layout_width="match_parent"
    android_layout_height="match_parent"

        android_layout_height="wrap_content"
        android_layout_gravity="bottom|end"
        android_layout_margin="@dimen/fab_margin"
        app_srcCompat="@android:drawable/ic_dialog_email" />

</android.support.design.widget.CoordinatorLayout>

ContentMain.xml

• Our ContentMain.xml file.
• Shall get inflated to MainActivity.
• Root tag is relativeLayout.
• Contains ListView with two columns.
• It is this ListView that we shall be searching.

<?xml version="1.0" encoding="utf-8"?>

<android.support.constraint.ConstraintLayout 
    
    
    android_layout_width="match_parent"
    android_layout_height="match_parent"
    app_layout_behavior="@string/appbar_scrolling_view_behavior"
    tools_context="com.tutorials.hp.searchbarlistview.MainActivity"
    tools_showIn="@layout/activity_main">

    <ListView
        android_id="@+id/mListView"
        android_layout_width="match_parent"
        android_layout_height="match_parent">
    </ListView>

</android.support.constraint.ConstraintLayout>
